What is it you are looking for? Most of the same information is in ev3sources. I am not sure of the current status of ev3sources. It is available at mindboards / ev3sources, but you may need to generate the documentation from the Doxyfile. Do you have that?

As Bluetooth for the EV3 uses a standard Linux bluez stack, there is not much to say about that this time.

The Lego documentation describes their byte codes and communication protocol, but these are not used by leJOS.

Mostly i want to see how lego previously did their bytecodes and communication protocol, to compare it to lejos. So if anyone have the documentation available that would be sweet (as all of the old links are broken on the lego site). I was also wondering if they had any plans of making something similar for the EV3. Do not have any plans of using them though, only comparing them as a different solution for a research paper.
